This cross-sectional study will include postmenopausal women under the age of 60 who visited the Physical Medicine and Rehabilitation outpatient clinic at Beylikdüzü State Hospital between June 25 and July 25, 2025. Participants must have undergone a bone mineral density (BMD) assessment within the past six months using Dual X-ray Absorptiometry (DXA). Both osteoporotic and non-osteoporotic patients will be enrolled. Sociodemographic data such as age, height, weight, and BMI will be recorded. Femoral neck and L1-L4 T-scores and BMD values will be obtained from existing DXA results. Information on osteoporosis treatment, presence of fecal incontinence, constipation, and medication use will be collected. In the second phase, sarcopenia will be assessed according to EWGSOP2 criteria using bioelectrical impedance analysis for skeletal muscle mass, handgrip strength, and the five-time sit-to-stand test. Differences between the osteoporotic and non-osteoporotic groups will be analyzed.
Women under 60 years of age who are postmenopausal.
Refusal to participate in the study.
Presence of neuromuscular diseases that could cause muscle loss.
History of infection, recent surgery, or trauma.
Presence of psychiatric disorders.
Postmenopausal women under 60 years
Case-control
Cross-sectional
Not listed
Skeletal Muscle Mass
Measured by bioelectrical impedance analysis (BIA), this assesses the amount of muscle tissue in the body. Low skeletal muscle mass indicates sarcopenia.
Handgrip Strength
This is a simple test to measure muscle strength. Reduced handgrip strength is a sign of sarcopenia.
5 times chair stand test
The Five Times Sit-to-Stand Test is a simple and widely used functional assessment tool to evaluate lower extremity muscle strength, balance, and mobility.
